Bill McCartney once led the University of Colorado to the ultimate prize in college football, and no football coach in school history has ever enjoyed as much success.
The life of McCartney, however, has been filled with as much heartache as triumph. ESPN's latest 30 for 30 special, "The Gospel According to Mac," doesn't pull any punches in telling the story of the man who is regarded as the greatest coach in CU football history.
The special, which debuted Tuesday night, runs about an hour and 41 minutes, not counting commercials.
